CVE-2025-49003
📋 TL;DR
This vulnerability allows remote code execution in DataEase by exploiting Java's character conversion behavior where 'ı' becomes 'I' and 'ſ' becomes 'S' when uppercased. Attackers can craft malicious messages that bypass security checks to execute arbitrary code. All DataEase installations prior to version 2.10.11 are affected.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to execute arbitrary code with application privileges, potentially leading to data theft, system takeover, or lateral movement.
Likely Case
Remote code execution leading to application compromise, data exfiltration, and potential privilege escalation.
If Mitigated
Limited impact if proper network segmentation, least privilege, and monitoring are in place, though RCE still poses significant risk.
🎯 Exploit Status
Exploitation requires crafting specific character sequences but doesn't require authentication.
